Those plans? To "just continue doing my business and growing my empire and have kids." (When she said growing my empire, for some reason I immediately heard this music in my head.)

She added that someday she'd like to have three or four children. When Letterman asked if she was currently having sex (Dave! Shame on you!), HIlton refrained from comment. But she did very happily show the talk show host how her new Paris Hilton app works. (Guess that app is part of the aforementioned continued empire growth.)

Watch a condensed version of the interview below, if only to remind yourself on this Friday that, at 30, Hilton already has far more money and business opportunities than most of us will ever have. No, it'll be a good thing. It will help you get in the mood for happy hour.
